The tentative contract is subject to ratification by the flight attendant membership, which is planned for first quarter 2014, Spirit said in a statement.

The new agreement, which was unanimously supported by the union’s leadership, was reached with the assistance of the National Mediation Board. Both parties have been in negotiation talks since 2007.

“We are pleased that we reached a mutually favorable agreement that recognizes our flight attendants for the great job they do every day for the company and our customers, while also supporting Spirit’s continued growth,” Spirit Chief Operating Officer John Bendoraitis said. “We look forward to working closely with our AFA partners and flight attendants to become the airline of choice for our customers and employer of choice for our team members.”
